The acute rupture occurs in collisions when the elbow is in flexion such as that in a wrestling match or a tackle in football. The ulnar collateral ligament distributes over fifty percent of the medial support of the elbow. [16] [17] This can result in an UCL injury or a dislocated elbow causing severe damage to the elbow and the radioulnar joints.
The ulna fractures in the proximal one-third of the shaft due to extreme dislocation. Depending on the impact and forces applied in each direction, degree of energy absorption determines pattern, involvement of the radial head and whether or not open soft tissue occurs. Direct blow on back of upper forearm would be a very uncommon cause.

Elbow dislocations constitute 10% to 25% of all injuries to the elbow. The elbow is one of the most commonly dislocated joints in the body, with an average annual incidence of acute dislocation of 6 per 100,000 persons. [30] Among injuries to the upper extremity, dislocation of the elbow is second only to a dislocated shoulder. A full ...
